As a Creator, you may be passionate about multiple endeavors. This is great! It might not make sense for you to open a ConvertKit account for every blog you own. However, there are some things so consider if you choose to do so.
Our general advice is:
If your blogs cater to different Segments of the same audience, then one ConvertKit account will work fine.
If they are separate blogs with distinct audiences, you will have an easier time creating a separate account for each blog.
We are not going to ban your account or stop you from managing email marketing for multiple sites in one account. But! Keep in mind that there are some ConvertKit features you may not get to take advantage of.
The 'All Subscribers' filter
ConvertKit was built to be Subscriber-centric, and this means you really only have one list. You can use Segments and Tags to carefully separate one audience from the other, but you won't ever want to use the 'All Subscribers' option when sending Broadcasts or creating Segments, as that will include Subscribers from both audiences.
If you have a Subscriber that has subscribed to both blogs, it is possible for them to Unsubscribe from both, while only intending to unsubscribe from one. We highly recommend you create custom unsubscribe links, as well as include explicit statements at the bottom of each email, as to what will happen if they click "Unsubscribe."
While you can use different "From" addresses on a per Sequence or per Broadcast basis, there is only one default for an account. You will need to change it every time you send a Broadcast if you'd like to send from a different address. And we can only create one custom domain per account, so you will need to choose which address you want to use.
Watch your Opt-Ins
Managing multiple blogs in one account can be tricky when it comes to opt-in consent. Remember that a subscriber opted in to a particular blog, not all blogs. They must consent before receiving any email from your other blog. Even if it's an accident, any unwanted email is considering spam, and can impact your engagement rates and account reputation going forward.
Best Practice: An Account for Every Distinct Audience
A fresh account for every distinct audience is the best practice and our advice. It allows you to avoid the obstacles outlined above. Please keep in mind that, because we don't advise running email marketing for multiple audiences, we cannot provide any support to doing so beyond this article.
Please note that this does not endorse multiple people sharing one account for separate businesses. This advice is for one business owner with several blogs, not for multiple business owners with individual blogs. We reserve the right to close your account if we determine you are sharing one account with others.
